BENJAMIN J. WILLIAMS, OF PHILADELPHIA, PENNSYLl/"ANML Letters .PatentNo. 102,900, lated May 10, 1870.

IMPROVED BLIND, SCREEN, AND SHUTTER.

The Scheduie referred to in these Letters Patent and making part of thesame.

` and operation ot' the same, reference being had to the accompanyingdrawings making a part of' this specification.l

Figure l is a front or inside view.

Figure 2 is a back or outside view. Figure 3 is atransverse sectionalview, in detail, of Venetian blind, as indicated by the line a J1 of'fig. .1,

`showing method of operating the slats.

Like letters in the figures of the drawings indicate like parts.

lhisinvention relates to aVenelian blind and inside folding shutter,provided with a wire screen or screens; and consists in combiningrtherewith certain devices l'or operating the slats,'as will` behereafter explained.

lo enable others skilled in the art to make and use my invention, I willproceed to describeits construetion and operation.

lhe Venetian blinds A and folding-slmtters `B are hinged together andhung to the frame C, as ordinaxily.

D are the wire screens, which are placed over* the slats on the outsideor back of the blind, and are sccured to the framing thereof by pieces,a, suitably beaded and joined together around and over the edge oi' `thewire, being glued and .nailed with cleat nails to the Stiles and railsforming the frame oi' the blind, or in any suitable manner that willsecure them wit-hout detracting from the finish ofthe blind.

E are the slats, which are arranged vertically to avoid the dustsettling on them, being pivoted to the rail above, as ordinarily, andbelow to two sliding. bars c c.

These bars are attached to the lever d by pivots, the lever beingattached to the center ot' the rail be.- tween the stiles by apivotscrew,'e.

A piece, 7i, is .let in across the stiles a little. above the rail,forminga slot in which the lever works. rlhis piece and the piece'on theback of the blind form the sides between which the bars work.

`tical in its adaptation for the purpose.

This method oi' operating the slats intended to be a simplication of thedevices patented for accomplishing the same thing, and is believed to belnore pracflhe opening and closing of thcslats for regulating theadmission ot' air and light being done as is obvious by working thelever laterally in the slot.

The bottom rails are provided with openings 0, to let the dust Vout thatwould otherwise accumulate thereon, and interfere with the bars slidingor working freely.

It, of course, will be understood that these blinds are to beconstructed. and provided with the wire screens, according to the roomor place designed to use them; as, for instance, in the windows of abedroom they may be so constructed as to make the room private, and yetafford ventilation and light and exclude insects at the same time, orthe panel shutters may be dispensed with anda full blind and screenused, 0r where full panel shutters are used in a hall and staircasewindow without blinds, the up ier panels of the lower section maybe leftout and slats with screens substituted in lieu thereof, and so on.

.Ii desirable, for the purpose oi'` giving a clear and unobstructed viewof thc street to thi.` person sitting at the window, the blinds of thelowerI section may be so hinged to the panel shutters on either side, asthat they may bc swung open without opening the shutters, the personhaving the benefit of a window-screen with sash hoisted.

Having thus fully described my invtmiion,

What I claim therein as new, and desire to secure by Letters Patent, isl The sliding bars c c and lever (I, as arranged and pivotcd to the railfor opera-ting the sltrl tion with a -Venetian blind and inside foldingshutter, provided with )vire screens D and openings o, substantially asdescribed.

As evidence that I claim the foregoing-as my invention, I have hereuntoset my hand and seal in the' presence ot two witnesses. t
